40 GHz Linear InGaAs PIN Photodetector

The Optilab PD-40 is a highly linear, 40 GHz bandwidth InGaAs PIN photodetector that is ideal for use in O/E front-ends requiring wide band frequency response. The coplanar waveguide photodiode design optimizes speed and sensitivity for the 1260 nm through 1610 nm wavelength range, and assures a 40 GHz frequency response necessary for digital and analog applications. The front-illuminated mesa-structured PIN design allows a high input power level of up to 10 mW. The PD-40 is available in a standard 2-pin package with K-connector output for ease of assembly, and can be ordered with or without the external protective housing. Contact Optilab for more information.
